HB-DA6EX

Electronic Balanced 6-way Stereo Distribution Amplifier




The HB-DA6EX is a professional audio distribution amplifier designed for broadcasting station and recording studio. The unit is suitable for mono, dual mono and/or stereo applications. It provides 2 inputs and 12 outputs. Each output can also be configured to receive Input A , Input B or a mono-derived sum from Input A+B. This is achieved via front panel toggle switches. Each output has own separate amplifier with individual gain-adjustable preset that can be accessed via the front panel.

The HB-DA6EX inputs and outputs are electronically balanced and can be wired unbalanced. Each output is individually buffered so that unbalanced or short-circuit on one output has no effect on any other output.

 

EASY OPERATION

The front panel is laid out clearly with 12 toggle switches and individual trim control for outputs configuration. Input A and Input B signals has two corresponding LED's that indicate signal content. The inputs level are adjustable using rotary control on the front panel.

The rear panel is equipped with two COMBO inputs to accept XLR or 6.3mm TRS jack balanced line level signals, and 12 XLRs outputs that can be selecting input source and adjust the output level.

 

FEATURES

  • High density, 2 balanced COMBO line level inputs, 12 electronically balanced outputs.
  • Gain adjustment ±12dB via multi-turn pre-set on each output.
  • Master Level controls for Input A and Input B.
  • Inputs and Outputs can be wired for unbalanced connection.
  • Mono / Stereo selection; each output can be individually to either input or to a stereo-summing of the inputs.
  • RFI filters on all inputs and outputs. EMC-proof case significantly improves rejection of radio frequency interference.
  • Output to connect additional HB-DA6EX for extra audio outputs.
  • LED indicators show signal contented of each input feed.
  • Switchable power supply (110V~120V or 220V~240V).
  • IEC-AC power receptacle.
